Summary of ChangesHello @huydanggdg, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the user interface of the Roman numeral converter application by introducing a dedicated CSS stylesheet. This styling is applied across both the input form and the conversion result page, providing a more polished and user-friendly experience. Furthermore, the input mechanism for numbers has been refined to ensure valid numerical entries within the typical range for Roman numeral conversions. Highlights

Code Review
This pull request introduces a new stylesheet and updates the HTML templates to create a much-improved user interface for the Roman numeral converter. The changes are well-structured, and the use of client-side validation on the input field is a great addition. My review includes a critical note about ensuring the backend can handle the form submission correctly, as the current implementation is likely to cause a runtime error. I've also included a few medium-severity suggestions regarding HTML best practices and file formatting.

While changing the input type to number is a good improvement for the user interface, it's important to ensure the backend handles the data correctly. Form data is always submitted as strings. In main.py, request.form["number"] will retrieve a string value. Passing this string to a function that expects an integer (like calendar.number_to_roman likely does) will cause a TypeError. The backend must explicitly convert the string to an integer and also handle potential conversion errors. For example:
try:
number_str = request.form["number"]
number_int = int(number_str)
except (KeyError, ValueError):
# Handle error: e.g., return an error page
return "Invalid input", 400
roman = calendar.number_to_roman(number_int)
# ...Without this server-side validation and type conversion, the application is likely to crash on submission.

The use of a <br> tag for creating vertical space is generally discouraged as it is not semantic. It's better to use CSS for styling and layout. You could add a margin-bottom to the preceding <p> element or a margin-top to the <a> element in your style.css to achieve the same visual result while keeping the HTML clean.

It's a common convention and good practice to have a newline at the end of files. Some tools and systems might have issues without it. Please add a newline at the end of this file.
